PerceptionVideoFrameAllocator 類別

定義

命名空間:

Windows.Devices.Perception.Provider

可直接建立 PerceptionFrame 的配置器，可直接寫入 Windows：：Media：：VideoFrame 或從 Windows：：Media：：VideoFrame 複製到 PerceptionFrame。

public sealed class PerceptionVideoFrameAllocator : System.IDisposable

function PerceptionVideoFrameAllocator(maxOutstandingFrameCountForWrite, format, resolution, alpha)

Public NotInheritable Class PerceptionVideoFrameAllocator
Implements IDisposable

繼承

Object Platform::Object IInspectable PerceptionVideoFrameAllocator

屬性

ActivatableAttribute ContractVersionAttribute MarshalingBehaviorAttribute ThreadingAttribute DeprecatedAttribute

實作

IClosable IDisposable

Windows 需求

裝置系列	Windows 10 (已於 10.0.10240.0 引進)
API contract	Windows.Foundation.UniversalApiContract (已於 v1.0 引進)

建構函式

PerceptionVideoFrameAllocator(UInt32, BitmapPixelFormat, Size, BitmapAlphaMode)

使用 IPerceptionFrameProvider 使用的必要屬性，初始化新的 PerceptionVideoFrameAllocator，以建立透過 PerceptionFrameProviderManagerService：:P ublishFrameForProvider 發佈的 PerceptionFrames。

方法

AllocateFrame()	使用建立 PerceptionVideoFrameAllocator 時所指定的屬性，建立空的 PerceptionFrame。
Close()	釋放由 Windows 執行階段 物件公開的系統資源。
CopyFromVideoFrame(VideoFrame)	建立影片 FrameProvider 的深層複本，其中包含已填入結果 PerceptionFrame 的位元組。
Dispose()	執行與釋放 (Free)、釋放 (Release) 或重設 Unmanaged 資源相關聯之應用程式定義的工作。
